Patent DE-2915942-A1 (DE)
Inventor: THIEMANN HANS
IPC: B21B37/52
Filed: 1979-04-20
Abstract: In a rolling plant having at least two mills (10, 20), the adjustment of the tension of the laminate is such that the rolling is effected in the boundary area where the tension cancels out. For this purpose a mill (20) having a number of rotations n2 is superposed with an additional rotation. Further, the mill (20) is superposed with an additional sinusoidal rotation. If the additional rotation equals 0 the absence of tension which prevails between the two mills (10) and (20) is maintained. However, a small loop will form and reabsorb at the rate of the sinusoidal oscillation. Hence, there will be no torque variation at the mill (10). If, during start of operation, the first sinusoidal half wave is positive, a torque variation at the mill (10) is recorded for that half wave and once only. Thereafter, there is no further moment variation. The additional rotation may be selected equal to or higher than the amplitude of the additional rotation. By changing the value of the additional rotation, it is also possible to modify the torque enrolling at the mill (10).

Title: Concrete plant loading hoist - has skip suspended from ropes engaging with hooks before entering weighing machine
IPC: B28C7/08
Filed: 1979-06-29
Abstract: The loading hoist is for a concrete batching plant, having a loading skip travelling between a low-level weighing machine and a high-level discharge point on a track, and entering and leaving the weighing machine at reduced speed. The skip (28) is suspended by two separate ropes (29), each reeved from a winch drum round a pulley (35) on the side of the skip to an arrester link (37) acting as an anchorage point. Normally this link fits over a support (40) on the skip itself, but as the skip travels into the weighing machine (30) it catches in an arrester hook (43) fixed to a stationary component. As the skip emerges from the weighing machine again, the link is freed from the hook and fits over the support on the skip again.

Title: Single disc force measurement bearing without housing - has strain gauges in holes and anti-twist gauges in countersunk holes and anti-twist cut=outs
Inventor: BROSA ERICH
IPC: G01L5/00
Filed: 1979-07-27
Abstract: The force measurement bearing of economical, very simple construction consists essentially of a single disc without a housing or bracket plate yet whose strain gauge measurement elements are extremely well protected. The ball bearing (1) or journal bearing fits into the disc (2) which has two diametrically opposed shear force measurement points. These are countersunk holes (3) with flat walls (4) receiving strain gauge elements which may be used for strain or shear force transducers. Cut-outs (8) are made in the disc to produce higher elasticity at the measurement points. These produce parallel flexible sections (9,10) which oppose movement of the bearing assembly (7) out of the plane and thus provide measurement point damage protection. It is a one-piece device apart from the hole caps and requires no other covers or stabilisation.

Patent DE-2942070-A1 (DE)
Title: Ultrasonic scanner and decoder - rectifies signal before digital conversion resolving single polarity signals using lower number of bits
Inventor: BORBURGH JACQUES DR ING
IPC: G01S7/52
Filed: 1979-10-17
Abstract: The ultrasonic scanner consists of a number of transducer elements (W1 to Wn) which emit signals that must then be processed. These signals are fed to a series of similar block units (B1 to Bn) built up from a number of circuit components e.g. amplifier, full wave rectifier, analogue-digital converter etc. and from there, the outputs of all these units (B1 to Bn) are fed to a digital adding device (19) for summing the signals. After a simple addition, the summing signal is fed to a coupled chain consisting of a digital equalising amplifier (20) and a digital demodulator (21) and finally to a rounding unit (23) via a digital filter (22) for bit-number reduction. This data reduced signal is then stored and displayed on a video tube, the system itself controlled by a central micro-processor unit (25) which also allows the programme of the block units (B1 to Bn) to be changed. The echo signal is rectified before analogue digital conversion, thus avoiding the high cost of a relatively high bit-number.

Patent DE-2944571-A1 (DE)
Title: Railway shunting system with maximised handling capacity - uses travel times for each section obtained from length and axle weightings
Inventor: KOENIG HELMUT DR ING
IPC: B61L17/00
Filed: 1979-11-05
Abstract: The system has each of the sections to be shunted, which differ in length and weight, arranged initially in a series sequence from which they are fed one at a time. Each section is discharged at a velocity which is higher than that of the preceding section until a terminal velocity is obtained. When a section is to be fed along a path corresponding at least in part to that followed by a preceding section, the system determines the spacing which must be allowed between them, in dependence on the travel time of each which is obtained in accordance with their length and axle weighting. When both sections are to be fed onto the same track, the times at which the rear and front buffers of the successive trains reach the same point is determined and the time difference between them compared with the previously obtained min. value so that the launching velocity of the second section can be reduced.
